Abstract: A wind turbine, power plant and associated method of controlling a wind turbine is provided. Data is obtained that identifies, based on forecast data, one or more future periods of time during which it would be desirable to over-rate the wind turbine, and measures of the fatigue life consumed by one or more turbine components are determined. The total fatigue life consumed by the one or more turbine components is limited prior to the one or more periods of time by controlling the power output of the wind turbine, in advance of the one or more periods of time, based upon the measure of the fatigue life consumed by the one or more turbine components.

Abstract: A wind turbine power plant comprises a plurality of wind turbines, each having a rated output and under the control of a power plant controller. The power plant also has a rated output which may be over-rated in response to one or more of electricity pricing data, power plant age and operator demand. The power plant controller can send over-rating demand signals to individual turbines. The controllers at the turbines include a fatigue life usage estimator which estimates a measure of the fatigue life consumed by key components of the turbine. If this measure exceeds a target value for any component, over-rating is prevented at that turbine.

Abstract: A method of generating a control schedule for a wind turbine is provided, the control schedule indicating how the turbine maximum power level varies over time, the method comprising: receiving input indicative of a target minimum wind turbine lifetime; determining a value indicative of the current remaining fatigue lifetime of the wind turbine or one or more turbine components, based on measured wind turbine site and/or operating data; and varying a parameter of an initial predefined control schedule that specifies how the turbine maximum power level varies over time. The parameter is varied by: (i) adjusting the parameter of the initial predefined control schedule; (ii) estimating the future fatigue lifetime consumed by the wind turbine or the one or more turbine components, over the duration of the varied control schedule, based upon the varied control schedule; and (iii) repeating steps (i) and (ii) until the estimated future fatigue lifetime consumed by the wind turbine or each of the one or more turbine components is sufficient to allow the target minimum wind turbine life to be reached.

Abstract: Generating a control schedule for a wind turbine, the control schedule indicating how the turbine maximum power level varies over time. Generating the control schedule includes determining a value indicative of the current remaining fatigue lifetime of the turbine, or one or more turbine components, based on measured wind turbine site and/or operating data; applying an optimisation function that varies an initial control schedule to determine an optimised control schedule by varying the trade off between energy capture and fatigue life consumed by the turbine or the one or more turbine components until an optimised control schedule is determined.

Abstract translation: 风力涡轮机发电厂包括多个风力涡轮机，每个风力涡轮机具有额定输出并且在发电厂控制器的控制下。 发电厂还有一个额定输出，可能会响应一个或多个电价定价数据，发电厂年龄和运营商的需求而被高估。 发电厂控制器可以向单个涡轮机发送超额功率信号。 涡轮机中的控制器包括疲劳寿命使用估计器，其估计涡轮机关键部件消耗的疲劳寿命的量度。 如果该措施超过任何部件的目标值，则在该涡轮机处防止超额定值。
